Current leakage wouldn't recommend this product to a friend

I bought 2 of these 3 years ago for my 150 gal FOWLR. They worked well for 2 1/2 years until they began having startup issues. I didn't think anything of it except that they needed maintenance. It wasn't until I installed a grounding rod that I found a problem. My GFI kept tripping and I narrowed it down to a Hydor circulator. I unplugged it and removed it and I found 2 large cracks in the housing. These were obviously allowing water into the electrical pump and causing a current leak. A few days later I removed the other Hydor and found cracks in the same place! I have suddenly lost 2 dwarf lion fish in the past 6 months who were very healthy the day before, and I can't help but think that this may have been a contributing factor. I now have some Tunze pumps, hopefully they will work out better.

High flow is very important to maintaining a thriving healthy aquarium. Aquariums with poor flow can experience a number of easily avoidable health issues. Using high flow powerheads in your aquarium will:

Significantly decrease the risk of algae outbreaks.

Keep waste and particles suspended longer so skimmers and filters have a better chance of removing them.
